Eruvim are symbolic boundaries installed where there are large Orthodox Jewish populations, allowing them to do things like carry keys, push strollers or carry groceries on the Sabbath and on Yom Kippur, when such activity is usually prohibited outside one’s home. They are made of string or wire enclosing the area. In many cases, the eruvim are made of PVC piping attached to utility poles.

"Our message to local officials in other towns who may be plotting to engage in similar attempts to illegally exclude, is the same: We will hold you accountable as well," Porrino said when the suit was announced earlier in October.
